UNIVERSAL HOOK.

Application filed .Tuly 18,

This invention relates to swivel or universally mounted supportingelements, and particularly to universal hooks.

The part-icular object of my invention is to provide an improveduniversal hook having a lubricant chamber or container therein to renderthe hook noiseless when in use.

Another object of the invention is to provide an improved and lubricateduniversal hook which has readily removable and renewable wear parts.Other objects of the invention are mentioned and described here- Thepreferred embodimentof my invention is illustrated in the accompanyingdrawing, wherein- Figure l represents an elevational and partiallysectional view of the assembled device;

Fig. 2 represents an elevational View of the supporting screw and itsbearing head;

Fig. 3 represents a view of the split abutment ring; and

Fig. 4 representsra modified form of the supporting element.

Similar numerals of reference indicate like parts throughout the severalviews on the drawing.

Referring to the details of the drawing the numeral l indicates aclyindrical cuplike socket element having the carrier hook 3 rigidlyconnected with the lower end wall 3 thereof at 4 in any suitable manner.

As illustrated, the hook shank is screw threaded into the end wall 3 ofthe socket element and has its upper end riveted or beadedv over tosecurely fasten it therein. The socket element l is provided with acylindrical bore or chamber 5 which is open at its upperv end andadapted to contain a lubricant and the assembly of the bearing elementshereinafter described.

The preferred structure of my invention contemplates a carrier orsupporting screw 6 adapted to be screwed into a wood frame of a porchswing, or other wood structurenot shown-and a spherical bearing head orball 7 rigidly mounted upon the lower end of said screw by threads 8, orotherwise, said bearing head being arranged within the chamber' 5 andbeing in universal engagement with the under surface of the annular'bearing rin 9. The ring 9 is removably fitted in the chamber 5 and bearsagainst an abutment ring 10, the latter being a transversely splitspring ring to enable its ready 1928. Serial No. 293,610.

application or removal from the annular groove ll in which it isnormally mounted and which is feraied in the wall of the bore 5 a l 'entthe top end thereof. The lower end of the screw G may be riveted orbeaded over at 13 and the head 7 may be formed with the transverse ridgel2 formed thereon receive suitable tool or wrench to ene the applicationof the bearing head 7 the l' .reads S. i

Then my improved universal hook is used for supporting` porch swings, 0rthe lil-Nic, and the chamber 5 iilled with suitable lubricant, it is anoiselcss article and free from disagreeable sounds due to the frictionresulting from movement of the swing when the latter heavily loaded.

l claim:

l. device of the character described compi ng a socket element providedwith a cup-like cylindrical lubricant chamber, a hook rigidly connectedwith the lower end oi' said socket element, a screw element providedwith a bearing head, the latter being arranged within said lubricantchamber and in engagement with and adapted for universal movement upon abearing ring removably mounted within said chamber, and removableabutment means for said bearing ring.

2. A device of the character described comprising a socket elementprovided with a cup-like cylindrical lubricant chamber, a lice-k rigidlyconnected with the lower end of said socket oiement, a ring-like bearingeieinent removably mounted within said lubi' t chamber, a screw elementprovided with a heini spherical bearing head, the latter being inengagement with said bearing ring and adapted for universal movementthereon, and a split spring abutment ring t0 maintain the juxtapositionof said bearing ring.

A device of the character described comprising a socket element providedwith a iubricant chamber open at its upper end, a bearir' ring mountedwithin said chamber, a screw eiement provided with a separate elementbear' y' head, the latter being in engagement said bearing ring andadapted movement thereon, and a hoo1 necred with the lower end of saidsociA ement.

4. A device of the character described compr a so let element providedwith a cylindi (JOE.

cal lubricant chamber Open at its upper end, ny bearing ring mountedwithin Suid chamber, a Screw element provided with e separate elementbearing head which is in engagement with said bearing ring and yadaptedfor universal movement thereon, Suid hearing head being provided with atransverse ridge adapted to receive a tool, sind :i hook connected withthe lower end of said socket element.

5. In combination, a socket element provided with a cylindricallubricant chamber open at its upper end, a bearing ring mounted Withinseid chamber, a bolt element provided with :i separate element bearinghead which is in engagement with Seid hearing ring and adapted foruniversel movement thereon, and :i hook connected with the lower end ofseid Soeliet element.
